Problems solved by technology

[0007] In practice, it has been proven that the dilators used in the aforementioned articles have certain disadvantages when used in the posterior region of the patient's maxilla, which is difficult to access and where there is little room to work during surgery. manipulative interocclusal space

Embodiment Construction

[0015] figure 1 Bottom, front and top views of a first embodiment of a bone crest expander-compactor according to the invention are shown. As seen in the figures, the dilator-compactor 1 comprises a head 2 , a threaded body 3 and a tip 4 . The head 2 serves as a connection area for a connector which can be connected to a medical motor in order to provide a motor-driven operation of the dilator-compactor 1 . As part of the expander-compactor, the threaded body 3 performs the actual expansion or compaction. As in other known dilators, the threaded body comprises a cylindrical threaded zone 5 and a conical threaded zone 6 . According to the invention, the length of the cylindrical threaded zone 5 is less than two-thirds of the length of the conical threaded zone 6 and the total length of the threaded zone 3 is less than 12 mm—by "length" is understood the dimension in the direction of the axis 17 . Both geometry and size provide the dilator-compactor 1 with a minimized size t...

Abstract

Motor-driven bone crest expander-compacter (1) whose geometry and dimensions have been redesigned to optimal values that allow the expander- compacter (1) to be used for bone expansion or compaction in rear areas of the patient's mouth. The expander-compacter (1) presents a threaded body (3) with a cylindrical threaded area (5) and a conical threaded area (6), where the cylindrical threaded area (5) presents a length smaller than two-thirds the length of the conical threaded area (6), in addition to the fact that the total length of the threaded body (3) is less than 12 mm. The invention also refers to a connector (7) connecting the expander-compacter (1) to a surgical motor, and to an initial burr (11), both of them equally optimised.

Description

technical field [0001] The present invention relates to a bone crest expander or tool for expanding or compacting a patient's bone crest prior to installation of a dental implant. Background technique [0002] The prior art includes bone crest expanders or compacters, which are tools used to expand or compact a patient's bone crest prior to installation of a dental implant. The dilator or compactor (hereinafter referred to as "dilator" or "dilator-compacter") may be driven manually or by a motor, in which case the dilator is connected to a connection operable by a medical motor device. [0003] The use of motor-driven dilators has several important clinical advantages over manual dilators. On the one hand, the control over the dilator entry direction (directionality) is more precise when the dilator is inserted using a micromotor rather than by hand. An important aspect to remember is that bones are often made of parts of different densities and that the spreader is prone...
